DESCRIPSION
The LM1117Q is a low power positive-voltage regulator designed to meet 1A output current and comply with
SCSI-II specifications with a fixed output voltage of 2.85V. This device is an excellent choice for use in battery-
powered applications, as active terminators for the SCSI bus, and portable computers. The LM1117Q features
very low quiescent current and very low dropout voltage of 1V at a full load and lower as output current
decreases. LM1117Q is available as an adjustable or fixed 1.2V, 1.5V, 1.8V, 2.5V, 2.85, 3.3V, and 5.0V output
voltages. The LM1117Q is offered in a 3-pin surface mount package SOT-223. The output capacitor of 10㎌ or
larger is needed for output stability of LM1117Q as required by most of the other regulator circuits.
